Procedure

5-[3-({[tert-Butyl(dimethyl)silyl]oxy}methyl)-2-fluorophenyl]-2-(piperazin-1-yl)pyrim idine (500 mg) was mixed with dichloromethane (10 ml), and DIPEA (482 mg) and 2-chloroethanesulfonyl chloride (304 mg) were added thereto at 0° C., followed by stirring at 0° C. for 1.5 hours. CHCl3 and water were added to the reaction mixture, and the organic layer was washed with water and saturated brine, dried over Na2SO4, and then concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (EtOAc/hexane) to obtain 5-[3-({[tert-butyl(dimethyl)silyl]oxy}methyl)-2-fluorophenyl]-2-[4-(vinylsulfonyl)piperazin-1-yl]pyrimidine (360 mg).
